So, may I present...
The Fluke meat thermometer with a PT1000! :D



Easter dinner with my brothers. 1331.8 Ohm was the target, man, it turned out perfectly!

Step 2: wirelessly send the temperature to the PC, then evaluate the target temperature and use your home automation system to turn off the oven once the meat is done ;)

Happy Easter.

It's nice to use what one has on hand, but keep in mind that digital thermometers with a spear tip (much better for meat) are under $3 delivered on eBay. :D

However definitely not that precise. You wouldn't want to miss that final touch to the tenderness of the meat that only a precise instrument can give. Nor would you want to spend more energy on heating the oven than necessary.

A loaf of meat has a specific heat of ~3 kJ/(kg * °C) (from here). The piece of meat in the op's picture looks about 2 kg in mass. Therefore we have an energy requirement of ~6 kJ/°C. Exceeding the target temperature by only 1 °C results in 6000 Ws of excess energy or 1.7 Wh.
There are ~ 2 billion adherents to christianity in the world (wolfram alpha). Assuming an average of 4 persons per household (my estimate), we get ~500 million households. Let only 0.1 % of those households have a tender piece of meat for Easter, that makes 500000 pieces of meat. If each piece is on the average 2 kg, then the energy wasted worldwide by overheating the Easter roast by 1 °C is
0.87 MWh

Doesn't this justify the investment in a good instrument? ;)
